i'm so glad they brought back tommy for buck. they could've brought back eli. they could've brought back the openly gay firefighter. they could've introduced someone new. but instead they brought back tommy: the guy who was stuck in the old boys' club, as well as figuring himself out around the same age as buck. the guy who wasn't warm or welcoming to chim or hen when they first arrived but who clearly struggled with doing so, and then who came to appreciate them and have their backs and enjoy their friendship. the guy who was there to see how bobby made a real difference to the 118, made it like a family before he left. the guy who was there for bobby's introduction of 'family dinners'. the guy who left the 118 so that buck could take his place there. the guy with the tk initials. the guy who shares a name with 2 other poignant tommys in the narrative for buck. the guy who chim called not once but twice for help and he answered. the guy who was saved by chimney and who will (hopefully) get to return the favour. the guy who made such pivitol personal growth in his time at the 118 thanks to chim and hen and bobby. they brought back the guy who proves that it's never too late to change, to grow, to be open and soft and caring. that it's never too late to learn about yourself, to figure out who you are as well as the person you want to be. that it's never too late to become a better version of yourself.
